Abstract

A single vertical column automatic balancing powerful rammer belongs to the engineering mechanical technique field. The complete machine is composed by a crawler, a frame, a single vertical column, a horizontal beam, a hoist, a lift hook, a single vertical column leveling device and a lifting load balancing device. During operation, the rammer falls within the support plane of the crawler which ensures stability of the complete machine. The single vertical column with blocked joints is characterized in simple structure and light weight which is simple to change the height of the single vertical column. The single vertical column leveling device is connected between the single vertical column and the frame, which will automatically adjust the verticality of the single vertical column when the ground is not level to avoid that the single vertical column suffers from bias load and fall point deviation of the rammer. When the rammer is lift and released, the downward loads acted on both ends of the horizontal beam will automatically become equal through adjustment of the lift load balancing device. The single vertical column bears only a vertical load passing the centerline of the vertical column without bending moment. Thus the single vertical column is under favorable load bearing characteristic, and when the rammer is released, the single vertical column shows no lateral bounce and small swing. The device applies to be used as geotechnical engineering construction equipment in powerful ramming operation.
